There are no valves in the unit. You can only regulate waterflow through this machine with self-supplied ball/gate valves

SOURCE: What is the gray gravely discharge coming from my PowerStar AE125 when using the hot water? It plugs up the faucet and shower heads within minutes and almost completely blocks the water flow.

Heating water can peculate chemicals out of water, such as metals and organics.
Especially above 138 degrees.
Have well water tested.
Turn down thermostat temperature.
Or reasonably harmless well-water bacteria can react with anode rod, or other reaction in softener, to produce colored water, and smells.
Different water can produce different sludges, brown, red, gray, black, yellow.
The sludge can also combine with deteriorating pipe flakes to clog water flow.
Sludge can accumulate over years in low spots in pipes, or at elbows and constrictions.
Have plumber flush pipes.
Or run new pipes.
Also delime tankless yearly, and flush with white vinegar as shown in product manual, and treat bacteria with H2O2 hydrogen peroxide.

My AE115 has power going to it but no hot water


make sure you have the water connections right. the inlet goes on the blue side. Also, your pressure must be a minimum of .8 psi. If not there will be no hot water and the neon will be off. other possible causes might be a crossover in your plumbing or a stuck flow transducer. Here is a link to a guide to explain how to check these items. http://efficientelectricwaterheaters.com/Tech-Support/PowerStar-Tech-Support.asp

Little to no flow through unit


Check for crossover:
http://waterheatertimer.org/Crossover.html
Clean water filter located just above where water enters unit.
Copy following link for Bosch powerstar manuals with brief troubleshoot section in each;
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html#manual
Call service technician who is qualified to work on computer that heats water. For plumbing problems, call local plumber. These are two different things.
Fix any brand tankless yourself, same day, by replacing the whole thing. Buy electric water heater at Lowes for $285 and be up and running by sundown.

AE115 has two elements and requires two 40 amp breakers.
A#125 has three elements and requires three 40 amp breakers, and is considered 'whole-house'
Do not install a tankless water heater because they cost more to install, and cost more to operate and maintain..

Have the 125. The light comes on on the panel, but water is usually ice cold. Have tried adjusting the thermostat but same results. Open to any suggestions on this matter. Thanks


Any suggestion could include a list of possible problems from bad PC board, burned out element, bad sensor, loose wire, or combination or these.
More information is needed to make a guess.
Test elements for continuity.
Check wires for loose and burned connections.
Open TP valve and test if hot water is available at machine.
If water at TP valve is hot, then problem might be plumbing-related, for example crossover.

1 Answer

Hot water tank does not work when shower is on, it does however work when the faucet in bathroom is on. It quit working in the shower about a month ago.


  1. COLD MIX, HEATER DEACTIVATES
    If inlet water temperature is over 70°F due to geographic location, water maybe very hot out of the tap. This requires a lot of cold water to be added with it in order to attain a useable hot water temperature. The addition of too much cold water will overpower hot water demand from the tankless water heater. This slows the flow within the tankless water heater, decreasing it below activation point, which shuts off the heater. The end result is nothing but cold water coming out of the outlet. See: TWH E2-04 Overcoming fluctuating temperatures [PDF].
  2. FLUCTUATING WATER PRESSURE
    If the water pressure in the home is erratic and the water flow is not consistent while a tap is opened, then the temperature of hot water will fluctuate. The minimum water pressure for the home should be 30psi or greater. For people on well systems the minimum pressure range is 30-50psi. The use of a pressure reducing/regulating valve is an effective way to maintain constant water pressure to the water heater. Watts brand 25AUB- ¾" or N35B-¾" pressure reducing/regulating valves or equivalent is suggested.
  3. CHANGING FLOW RATE
    Major changes in flow rate can adversely affect the output water temperature of the heater. Increases from one major fixture running to multiple fixtures running at one time can cause the temperature to fluctuate. Stay within the heater's specifications. See: TWH E2-03 Outlet temperature vs. flow rate [PDF].

Good Luck,

The easiest thing to do would be to call Bosch and just ask for a new heater for free. The other option is to call Bosch and have them send you all new elements. If there is power, there should be heat of some kind.

Seems it doesnt come on unless i turn on two


This is a common problem. They are desighned to come on when a certain volume of water goes through it and with todays low flow water conserving devises they don't always come on with one faucette.

You can have a loop installed that allows a higher volume of water to flow when a valve is turned on. It simply flows back into the supply side of the unit.
